Amp protection lights on

Interesting comment by Gene Delasrio in his review of LBM speakers.......
"Class-A/B may not be quite as efficient as class-D, but it is more reliable on the whole, and with such a massive heatsink, it looks like a unit that was built to last."

Looks can be deceiving. Those amps are not particularly long lived, because of design problems. Class A/B amps are not inherently longer lived than class D.

Correction to my post....that review was James Larson.
He states in another article
"So what then is the advantage of an analog amp? Lower-cost analog amps tend to be more reliable than lower-cost class-D amps. Analog amps can also have more headroom than a similarly rated Class D w SMPS amp."

Perhaps his caveat is "low cost" class D amps. Maybe his concern is the power supply. I think those are modular and user replacable on Buckeye amps.
